mailto with space after colon parses incorrectly (but is not against spec)

[zkamvar]

Spaces for mailto links must be formatted with the escape code %20, including after the colon. This is in accordance with the commonmark spec (CommonMark Spec: Link Destination)

Examples:

• works (no space): email
• also works (escaped space): email
• fails: [email](mailto: zkamvar@example.com)

In tinkr:

mailto with no space works:

tinkr::yarn$new(textConnection("[link](mailto:zkamvar@example.com)\n"))$body |> xml2::xml_child() |> as.character() |> writeLines()
#> <paragraph>
#>   <link destination="mailto:zkamvar@example.com" title="">
#>     <text xml:space="preserve">link</text>
#>   </link>
#> </paragraph>

mailto with a space converts it to text with an internal mailto link (since the email is automatically converted)

tinkr::yarn$new(textConnection("[link](mailto: zkamvar@example.com)\n"))$body |> xml2::xml_child() |> as.character() |> writeLines()
#> <paragraph>
#>   <text xml:space="preserve">[link](mailto: </text>
#>   <link destination="mailto:zkamvar@example.com" title="">
#>     <text xml:space="preserve">zkamvar@example.com</text>
#>   </link>
#>   <text xml:space="preserve">)</text>
#> </paragraph>

I am leaving this here just in case anyone else runs into this issue and wants to know the fix.
